This very short (95 pages) book borders on being a pamphlet. The big drive of the book is to show that North Korea remains continually hostile to the South, ever since their "hot war" of the 1950's. If you already knew that, then you don't need this book; it doesn't elaborate much further than that. It is written in an extremely simplistic style, so may be well-suited for something like a junior high school student writing a report on Korea.
